Description
editProstanthera lanceolata is an erect, aromatic shrub that typically grows to a height of 3–4 m (9.8–13.1 ft) and has branches that are square in cross-section. The leaves are mid to dark green, paler below, narrow egg-shaped to egg-shaped, 15–25 mm (0.59–0.98 in) long and 9–12 mm (0.35–0.47 in) wide on a petiole 2–5 mm (0.079–0.197 in) long. The flowers are arranged in bunches near the ends of branchlets with bracteoles about 1 mm (0.039 in) long at the base, but that fall off as the flower develops. The sepals are about 4 mm (0.16 in) long, forming a tube about 2 mm (0.079 in) long with two lobes, the upper lobe 1.5–2 mm (0.059–0.079 in) long. The petals are mauve to deep bluish-purple and 8–12 mm (0.31–0.47 in) long. Flowering occurs in spring.[2] This species is included in Prostanthera ovalifolia in Queensland.[1]
